we have evaluated your "VintaSoft Annotation Demo (ASP.NET WebForms)" . it meets most of our requirements. We are trying to integrate with our product. we are facing couple of challenges, if you could resolve these issues we will proceed with purchase.
1.We are not able to specify the upload path . Image should get saved in images server which we have set in config file.
2.We are not able to set the download Path . Image should get displayed from specific path where we dump required images.
3.Is there any feature where Annotation should be saved as separate layer , it should not tamper original image.
4.How to set scanner settings without showing scanner UI to user.
